We will cover this later but the last variable will set the default performance threshold in this case 5 seconds.

我们将会在后面提到它。最后一个变量将会对创建的性能进行设置，这里是5秒。

The conclusion then drawn by some observers is that, indeed, once above a certain performance threshold, amplifiers do sound alike.

结论，然后得出一些观察家的是，事实上，一旦超过某个阈值的性能，放大器不健全的乐趣。
